Part) and Die Protection is active (not bypassed) then the count will increment
whenever a part is seen by this input. (Remember that the part counter must still
be set active for counting to take place as noted earlier). If an input is
programmed as a Part Detector but Die Protection is bypassed, no counting will
take place.
2. If no Die Protection input is programmed as a Part Detector then the part counter
will increment at 270 degrees just as the stroke counter. In this mode the counter
acts as a presettable stroke counter which can stop the machine.
Once the counter reaches the parts count limit, the System 2500 PLS will generate a top stop for
the machine. (See Section 2.5.3 for description of the Topstop function). When the operator is
ready to restart the machine the top stop can be removed by pressing the CLEAR key. Clearing
the top stop also resets the part counter to zero.
If the keyswitch is in the PROG position, the counter operation can be programmed by the
operator. The part counter can be turned off (no counting whatsoever) by pressing the DOWN
arrow key, or turned on by pressing the UP arrow key. If the part counter is not being used, it
should be turned off. The counter can be reset to zero by pressing the '-' (dash) key. (Be careful
not to reset the counter accidentally!) Also, the Part Count Limit can be changed by keying in
the desired value and pressing the ENTER key. This limit is the count at which a top stop will be
issued to the machine. The maximum count limit is 999999.
2.6.2 BATCH Counter
The batch counter is used to count the number of strokes per batch. If a total part run is to
contain several batches (such as parts per box), the batch counter can be used to stop the process
after each batch limit has been reached.
The batch counter operates in exactly the same manner as the part counter. The counting
function is tied to the Part Detector portion of Die Protection in the same way that the part
counter is tied. All operations on the batch counter such as turning on, turning off, resetting, and
entry of the batch count limit are performed by the operator in the same way as for the part
counter. If the batch counter is not being used, it should be deactivated.
2.6.3 QUALITY Counter
The quality counter is used to count the number of strokes between quality control checks. The
quality counter operates in exactly the same manner as the part counter. The counting function is
tied to the Part Detector portion of Die Protection in the same way that the part counter is tied.
All operations on the quality counter such as turning on, turning off, resetting, and entry of the
